  1. 11. Studies of Dark Showers for Present and Future Colliders

    University essay from Lunds universitet/Partikel- och kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Nicoline Krogh Hemme; [2022]
    Keywords : high-energy particle physics; dark matter; collider physics; beyond the standard model; Physics and Astronomy;

    Abstract : In this work we explore a strongly-interacting dark sector with a Z’ portal to the Standard Model. We focus on the dark shower phenomenology and their semi-visible jet signatures with a strong emphasis on first principles of the theory. READ MORE

  3. 12. Exploring a Two Higgs Doublet Model with a U(1) Family Symmetry and a Complex Singlet

    University essay from Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation

    Author : Michal Nowak; [2021]
    Keywords : Two Higgs Doublet Model; Complex Singlet Extension; Phenomenology; Physics Beyond the Standard Model; Branco-Grimus-Lavoura Model; Physics and Astronomy;

    Abstract : In this project a two Higgs doublet model with a complex singlet and an extra family symmetry providing a mechanism for suppression of flavor changing neutral currents is explored. The goal is to investigate the phenomenological consistency of the model using a custom software framework. READ MORE

  4. 13. Beyond high mutation highrecombination limit in statisticalgenetics

    University essay from KTH/Fysik

    Author : Luc Zorrilla; [2021]
    Keywords : Statistical Genetics; Population genetics; Statistical physics; Linkage Equilibrium;

    Abstract : One considers the bi-allelic model in population genetics which describes a population of genomes evolving under the processes of selection, mutation, recombination and drift. A focus is made on the Quasi-Linkage Equilibrium (QLE) phase with recent derivations from Neher and Shraiman, which exists for fast recombinations compared to selection strength and whose dynamics is greatly simplified compared to the general case.

  5. 14. Sterile Neutrinos and Non-Standard Interactions in Neutrino Telescopes

    University essay from KTH/Fysik

    Author : Martin Sjöborg; [2021]
    Keywords : ;

    Abstract : The failure of the Standard Model of particle physics to predict neutrino masses invites us to amend it. We have no reason to believe that the interactions currently described by the gauge group are the whole picture, nor should we expect that the number of fermions hitherto observed is correct.

  6. 15. Flavour Symmetries in SU(5) Grand Unified Theories

    University essay from KTH/Fysik

    Author : Malte Lindestam; [2021]
    Keywords : ;

    Abstract : The current description of physics on the very smallest scales is given by the standard model (SM) of particle physics. It makes many good predictions and is a highly successful theory. There are however phenomena it cannot explain, and it is therefore not a complete theory of particle physics. READ MORE
